Lycium barbarum polysaccharides enhance testicular spermatogenesis in d‐galactose‐induced aging rats via calcium signaling

Andrology, Volume 14, Issue 2, Page 496-515, February 2026.
Abstract Background Lycium barbarum polysaccharide (LBP) has long been recognized as having a wide range of beneficial properties for improving proliferation. However, the protective effects and specific mechanisms of d‐galactose‐induced testicular dysfunction in reproductively senescent rats are not fully understood.

Exploring Repro‐Timing Harm and Benefit

Bioethics, Volume 40, Issue 2, Page 201-210, February 2026.
ABSTRACT It is plausible that time of birth affects one's prospects for wellbeing. Being born during a war or recession might have a negative impact on early life and lifetime wellbeing. In natural reproduction, delaying conception does not result in the same child being born later, but rather a different child altogether; therefore, prospective ...

Establishment and optimization of the two‐step induction system for generating primordial germ cell‐like cells from chicken embryonic stem cells

FEBS Open Bio, Volume 16, Issue 1, Page 161-177, January 2026.
This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.
